FLIER CONSTRUCTION Filed April 7. 1931 '15; the removal of the fliers to a separate bench or Patented Oct. 16, 1934 UNITED STATES,

PATENT. omcs 8 Claims.

This invention relates to improvements in flier blocks and more particularly to a novel detachable anti-ballooning device for spinning machines.

Hitherto it has been proposed to, use so-called Figure 8 fliers for preventing ballooning of the threads on a spinning machine. These devices are usually hand made and are formed directly on the flier block with which they are to be used and, usually, are formed integral with the flier arms. When it is desired to replace the Figure 8 flier unit with the straight arm or drop arm type or vice versa it is necessary to remove the wires from the block and rewire. This procedurerequires machine shop and renders the, machine either temporarily idle or requires the substitution of other blocks during the rewiring.

It is an object of this invention to provide an improved demountable anti-ballooning device for spinning machine fliers.

, Itis another object of this invention to provide such an improved anti-ballooning device which may be readily inserted and removed from a flier.

. Yet another object of this invention is the provision of an improved anti-ballooning device which issusceptible of various configurations.

Still another object of this invention is the provision of an improved detachable anti-ballooning device providing a minimum of threadbearing contact. 7 7

These and other desirable objects and advantages of the present invention will be described in the accompanying specification and illustrated in the drawing, certain preferred embodiments being shown by Way of example only for, since the underlying features may be incorporated in other specific mechanical devices it is not intended to be limited to the ones here shown except as such limitations are clearly imposed by the appended claims.

In the drawing like numerals refer'to similar partsthroughout the several views of which Fig. 1 is an elevation of a bobbin with an attached flier and an improved anti-ballooning member;

Fig. 2 is a top plan view of structure shown in i 1;

Fig. 3 is an elevation of the anti-ballooning device shown in Figs. 1 and 2;

Figs. 4, 5 and 6 are views similar to those shown and show a modified form of anti-ballooning devices.

Broadly considered the novel improvements of the present invention comprehend the utilization of a detachable guiding member or anti-ballooning device for use in connecton with flier constructions, more particularly of the type shown and described in my applications Serial Nos. 458,210, filed May 31, 1930; 458,211, filed May 31, 1930; 458,212, filed May 31, 1930; 489,401, filed Oct. 17, 1930; and 507,676, filed January 9, 1931.

Referring now to the drawing there is shown a bobbin 1 mounted for rotation on spindle'2, with which is associated a flier 3 of any desired construction and which as shown in Fig. 1 may comprise a block having a wire'retaining platform 4 adapted to receive a flier wire 5, the latter being held in position by means of a clamping member 6. The flier block shown may include a footed member of the eccentric foot type as shown in my applications Serial Nos. 458,212 and 489,401, above referred to or of a concentric foot of the type shown in my application Serial No. 517,023. If desired the flier block may be of the general type shown in Fig. 4 comprising a hub 7 with a'wire retaining skirt 8 provided with opposed slots 9 adapted to maintain a flier arm 5 in operative position. These blocks may, as usual, comprise footed members adapted for use with bobbins having locking bushings in the top thereof or may include spring means adapted for. retaining the blocks on uniformly tapered spindles. These constructions are severally shown in my applications above identified and are not claimed herein except in the novel combinations hereinafter to be set forth.

Referring more particularly to Figs. 1, 2 and 3 the anti-ballooning device of the present inventioncomprises a top body portion 10 which is so configured as to present substantially a figure S, designated generally by the numeral 11 with parallel sidearms 12 bent back'fr'om the ends of the S and forming with the legs thereof a substantially rectangular member having spaces 13 between the side members opening into thread receiving channels or apertures 14. The members12 are continuedto form depending legs 15 of any suitable length which terminate in angular extensions 16 adapted-for locking engagement with a'flier block. As shown in Fig.1 the locking engagement may be by means of a clamping member 6 or, as shown in Fig. 4, the members 16 may be inserted into apertures 9 of 1 block 7 and be held in position by means of their own resilience, these retaining members being of sufficient length to secure the desired result. By varying the angularity of members 16 with respect to member 15 they may be sprung into position and held, as above noted, by their own resilience.

Thread receiving loops of the flier arms 5 cooperate with the sections 14 of the member to provide the desired tension for the thread and prevent its ballooning during the spinning operation. The threads may be usually slipped into place through the apertures 13 without requiring any threading. It will be noted that with the construction shown a minimum of bearing contact on the supports 15 is provided for the threads thus preventing any oil or dust which may be accumulated thereon from being picked up by the thread in its travel and thus be incorporated into the finished woven product. 5

The construction described, can readily be made from wire of any suitable size and is characterized by the ease of attachment and detachment without requiring the formation of an entire new anti-ballooning device and flier arm as has heretofore been required. These members may be pre-formed as are the flier arms and permit a marked degree of flexibility in spinning operations which has not heretofore beenpossible.

While the construction shown in Figs. 1, 2 and 3 may be used, when desired, the invention also comprehends the use of looped members similar in construction to those shown, with the exception that the thread receiving or guiding portion is formed by a loop formed integral in the wire. These loops are shown more particularly in Figs. 4 to 6 inclusive, the remainder of the structure being similar to that already described.

Any desired configuration may be given to the sections 10 and 20 of the anti-ballooning devices and it will be appreciated that the retaining means may also be varied. The retaining means associated with the flier blocks may, as intimated,

' be of any suitable type, being either demounta flier wire retaining platform, a flier w1re seated able or integral, the former including screwthreaded means or caps as well as bayonet jointed members.

It will now be appreciated that there has been provided certain novel improvements in flier con structions for spinning machines and more par ticularly certain improved demountable anti-ballooning devices adapted for use with flier arms of any approved type and without requiring the formation of a new unit every time it is desired to change to an anti-balloon construction or vice versa.
